Product Description

The YUXIANG EOCH-MSH620-FXARM high-back ergonomic mesh office chair balances professional visual appeal with purpose-built functional design for extended seated use. Its structured layout features a tall, contoured mesh backrest paired with a wide, padded seat, fixed integrated loop armrests aligned to the back frame, and a supportive height-adjustable headrest, all mounted atop a stable five-star caster base that enables full 360-degree swivel movement. The chair presents a streamlined, modern silhouette that fits seamlessly across both commercial and residential interior styles without unnecessary bulk. Construction prioritizes durability and long-term comfort. The backrest uses breathable polyester tension mesh stretched over a glass-fiber reinforced polypropylene frame, with a built-in contoured lumbar zone for consistent lower back support. The headrest is a mesh-covered polypropylene pad mounted on an adjustable bracket, while the seat core consists of high-density molded polyurethane foam topped with fabric upholstery, finished with a contoured waterfall front edge to reduce pressure on the backs of the legs. The integrated fixed armrests are constructed from polypropylene, connected directly to the back frame for structural stability. The base is an injection-molded nylon and polypropylene five-star unit fitted with 60mm nylon dual-wheel swivel casters, paired with a Class 3 pneumatic steel gas lift for height adjustment and a 2.5mm thick steel butterfly tilt-lock chassis under the seat. The mesh upholstery is engineered to withstand heavy repeated use, with tested abrasion resistance, while the seat foam delivers consistent rebound for lasting cushioning, and casters operate at a low noise level to avoid disrupting shared spaces. Practical functions are tailored to varied user needs. The seat offers 100mm of vertical height adjustment via an under-seat pneumatic lever, while the backrest supports 3-position lockable recline up to 125 degrees, with weight-activated automatic tension adjustment to deliver balanced recline resistance for different users. The height-adjustable headrest can be positioned to support optimal neck alignment, and the dual-wheel casters roll smoothly across hard floors and low-pile carpet for easy repositioning. The breathable mesh back reduces heat buildup during long periods of sitting, supporting comfort across full workdays. This chair is suited for a wide range of settings, including open-plan office workstations for staff completing 8+ hours of daily desk work, compact home office study spaces for remote workers, conference and meeting rooms supporting collaborative discussion, computer and IT work areas with extended screen use, high-traffic reception and administrative zones, and flexible training room installations. For procurement teams, key considerations include that each unit ships across two cartons, with a 40-minute reference assembly time per set. The chair holds a recommended maximum user weight of 150 kg, with a high static load rating for the five-star base, and 135 sets can be loaded in a 20GP container at 85% space utilization, supporting efficient bulk order planning for large-scale fit-outs.
